The PRO401HH can also use any type of 50 Ω / 27 MHz band
antenna. Although a telescoping antenna might provide better
transmission and receiving, it is not as compact or easy to use as
the antenna included in the package.
CONNECTING TO POWER
Your PRO401HH can operate on DC power or batteries.
DC Power
